CHAPTER CHECKLIST When you have completed your study of this chapter, you will be able to 1 Explain how a rent ceiling creates a housing shortage, inefficiency, and unfairness. 2 Explain how the minimum wage creates unemployment, inefficiency, and unfairness. 3 Explain how production quotas create inefficiency and unfairness. 7.1 PRICE CEILINGS A Rent Ceiling Rent ceiling A government regulation that makes it illegal to charge more than a specified rent for housing. Price ceiling The highest price at which it is legal to trade a particular good, service, or factor of production. A rent ceiling is an example of a price ceiling. 7.1 PRICE CEILINGS Figure 7.1 shows a housing market. The demand for and supply of housing determine the equilibrium rent of $550 a month and the equilibrium quantity of 4,000 units of housing. 7.1 PRICE CEILINGS Figure 7.2 shows how a rent ceiling creates a shortage. A rent ceiling is imposed below the equilibrium rent at $400 a month. 1. The quantity of housing supplied decreases to 3,000 units. 2. The quantity of housing demanded increases to 6,000 units. 3. A shortage of 3,000 units arises. 7.1 PRICE CEILINGS When a rent ceiling creates a housing shortage, two developments occur: • A black market • Increased search activity Black market An illegal market that operates alongside a governmentregulated market. Search activity The time spent looking for someone with whom to do business. 7.1 PRICE CEILINGS Figure 7.3 shows how a rent ceiling creates a black market and housing search. With a rent ceiling of $400 a month: 1. 3,000 units of housing are available. 2. Someone is willing to pay $625 a month for the 3,000th unit of housing. 7.1 PRICE CEILINGS 3. Black market rents might be as high as $625 a month and resources get used up in costly search activity. 7.1 PRICE CEILINGS Are Rent Ceilings Efficient? With a rent ceiling, the outcome is inefficient. Marginal benefit exceeds marginal cost. Producer surplus and consumer surplus shrink, and a deadweight loss arises. People who can’t find housing and landlords who can’t offer housing at a lower rent lose. 7.1 PRICE CEILINGS Figure 7.4(a) shows an efficient housing market. 1. The market is efficient with marginal benefit equal to marginal cost. 2. Consumer surplus and producer surplus are as large as possible. 7.1 PRICE CEILINGS Figure 7.4(b) shows the inefficiency of a rent ceiling. 1. A rent ceiling restricts the quantity supplied and marginal benefit exceeds marginal cost. 2. Consumer surplus (green area) and producer surplus (blue area) shrink 7.1 PRICE CEILINGS 3. A deadweight loss arises. 4. Other resources are lost in search activity and evading and enforcing the rent ceiling law . Resource use is inefficient. 7.1 PRICE CEILINGS Are Rent Ceilings Fair? Are the rules fair? Are the results fair? Does blocking rent adjustments avoid scarcity? What mechanisms allocate resources when prices don’t do the job? Are those non-price mechanisms fair? 7.1 PRICE CEILINGS If Rent Ceilings Are So Bad,Why Do We Have Them? Current renters gain and lobby politicians. More renters than landlords, so rent ceilings can tip an election. 7.2 PRICE FLOORS The labor market influences employment opportunities and wage rates. Figure 7.5 shows a market for fast-food servers The demand for and supply of fast-food servers determine the equilibrium wage rate of $5 an hour and the equilibrium quantity of 5,000 servers employed. 7.2 PRICE FLOORS The Minimum Wage Minimum wage law A government regulation that makes hiring labor for less than a specified wage illegal. Price floor The lowest price at which it is legal to trade a particular good, service, or factor of production. The minimum wage is an example of a price floor. 7.2 PRICE FLOORS Figure 7.6 shows how a minimum wage creates unemployment. A minimum wage is introduced at $7 an hour. 1. The quantity of labor demanded decreases to 3,000 workers. 2. The quantity of labor supplied increases to 7,000 people. 3. 4,000 people are unemployed. 7.2 PRICE FLOORS Figure 7.7 shows how a minimum wage increases job search. 1. At the minimum wage rate of $7 an hour, 3,000 jobs are available. 2. Someone is willing to take the 3,000th job for $3 an hour. 7.2 PRICE FLOORS 3. Illegal wage rates might range from just below $7 an hour to $3 an hour. People are willing to spend time on job search that is worth the equivalent of lowering their wage rate by $4 an hour. 7.2 PRICE FLOORS Is the Minimum Wage Efficient? The firms’ surplus and workers’ surplus shrink, and a deadweight loss arises. Firms that cut back employment and by people who can’t find jobs at the higher wage rate lose. The total loss exceeds the deadweight loss because resources get used in costly job-search activity. 7.2 PRICE FLOORS Figure 7.8(a) shows an efficient labor market. 1. At the market equilibrium, the marginal benefit of labor to firms equals the marginal cost of working. 2. The firms’ and workers’ surpluses are as large as possible. 7.2 PRICE FLOORS Figure 7.8(b) shows an inefficient labor market with a minimum wage. 1. The minimum wage restricts the quantity demanded. 2. The firms’ surplus and the workers’ surplus shrinks. 7.2 PRICE FLOORS 3. A deadweight loss arises. 4. Other resources are used up in job search activity The outcome is inefficient. 7.2 PRICE FLOORS Is the Minimum Wage Fair? Is the rule fair? Is the result fair? If the wage rate doesn’t allocate labor, what does? Are non-wage allocation mechanisms fair? 7.2 PRICE FLOORS If the Minimum Wage Is So Bad,Why Do We Have It? The effects of minimum wage on employment might be small. What would make the effects on employment small? Labor unions might lobby for a minimum wage: why? 7.3 PRODUCTION QUOTAS A Production Quota Production quota An upper limit to the quantity of a good that may be produced in a specified time period. 7.3 PRODUCTION QUOTAS Figure 7.9 shows a market for sugar beets. 1. With no government intervention, the market is in equilibrium where the quantity demanded equals the quantity supplied. 2. The equilibrium price is $30 a ton and 3. the equilibrium quantity is 60 million tons a year 7.3 PRODUCTION QUOTAS Figure 7.10 shows the effects of a production quota set below the equilibrium quantity at 40 million tons a year. 1. The price rises, and … 2. marginal cost falls. 7.3 PRODUCTION QUOTAS Is a Production Quota Efficient or Fair? A production quota is inefficient. It results in a quantity at which marginal benefit exceeds marginal cost so that a deadweight loss arises. Whether a quota is fair depends on a lot of details about the incomes and economic status of producers and consumers. The general presumption is that the producer gains an unfair advantage and the consumer is unfairly penalized. 7.3 PRODUCTION QUOTAS Figure 7.11 shows the inefficiency of a production quota. Without a quota, 1. The market equilibrium is efficient and the sum of 2. consumer surplus and 3. producer surplus is maximized. 7.3 PRODUCTION QUOTAS With a quota, 1. The quantity decreases. 2. Consumer surplus shrinks. 3. Producer surplus expands. 4. A deadweight loss arises.
